To all whom it-may concern.

Be it known that we, JOHN COPE BUTTER- FIELD and TELFORD CLARENCE BA'roHELoR, subjects of the Queen of Great Britain, residing at London, England, have invented certain new and useful Improvements in the Construction of Damp-Proof Cartridge-Cases, of which the following is a specification, the same having been patented in England upon an application, No. 15,160, filed October '22, 1888; in

France, No. 193,950, dated November 6, 1888; in Belgium, No. 83,828, dated November 3, 1888; in Germany upon an application, No. K. B. 13,936, filed November 3, 1888; in Spain, upon an application filed N0vember17, 1888; and in Canada, No..30,328, dated December 1, 1888.

This invention relates to damp-proof cartridge-cases, such as when charged may be used for mining purposes, and has for its principal object the constructionof such'cases preferably of metal, such as lead, lead and antimony, or lead and tin, but which may be of vulcanite or some such water-proof material.

In the accompai'iyingdrawings, Figure 1 is a longitudinal section of one form of the cartridge-case charged and ready for use. Fig; 2 is a similar, view of the same partly filled and without the fuse or match.

\Vith reference t0 Figs. 1 and 2, A is'the main inclosing portion, which, together with the closed end A, preferably'made in part of a hollow cylinder, with some of the said' loose explosive material contained within it.

which passes through the stuffing-box and When constructing the cartridge the explosive D is introduced through the then open end of the shell A, and the cap Bis af-' terward placed over the said end, a tight joint being made between the parts A and B gland B screwed farther onto the stuffing box'B, so that the packing O is pressed and 6c clamped tightly around. the said fuse, thus completing the hermetic'closing of the cartridge, which is thereby rendered impervious to {dampness orwater.

Instead of forming the stuffing-boXB on'65 I the cap '13, we may form it on the closed end A and use a plain cap; as will be readily understood. 1

Having thusdescribed our invention, what we claim as new is 1 7 1. In a damp-proof cartridge, the combination,,wi.th the casin g having the permanently- .closed end and the cap on the opposite end, of the screw-threaded stuffing-box 'surrounding the fuse, the packing, and the gland for pressing thepack'ing around the fuse, substantially as'described. v I 7 f I .2, In a cartridge, the combination, with a shell having one permanently-closedend, of 7 a separate cap provided with a 'stufli'ng hav ing packing, and a gland for pressingthe packing around the fuse for closing in the other end, substantiallyas herein described, and illustrated in the accompanying draw ings. p 4 p 5: In witnesswhereof'we"have heretoset our hands 'inthe' presence of the two subscribing witnesses:
